Many engineers have 1 their function the designing of products that are to be brought into reality through the processing or fabrication of materials. In this capacity they are a key factor in the material selection—manufacturing procedure. A design engineer, better than any other person, should know what he or she wants a design to accomplish. He knows what assumptions he has made about service loads and requirements, what service environment the product must withstand, and what appearance he wants the final product to have. In order to meet these requirements he must select and specify the material (s) to be used. In most 2 , in order to utilize the material and to enable the product to have the desired form, he knows that certain manufacturing processes will have to be employed. In many 3 , the selection of a specific material may dictate what processing must be used. At the 4
time, when certain processes are to be used, the design may have to be modified in order for the process to be utilized effectively and economically. Certain dimensional tolerances can dictate the processing. In any case, in the 5 of converting the design into reality, such decisions must be made by someone. In most instances they can be made most effectively at the design stage, by the designer if he has a reasonably adequate knowledge 6 materials and manufacturing processes. 7 , decisions may be 8 that will detract from the effectiveness of the product, or the product may be needlessly costly. It is 9
apparent that design engineers 10 a vital factor in the manufacturing process, and it is indeed a blessing to the company if they can design for productivity that is, for efficient production .
